Extending the Recording Time
The total continuous recording time can be extended by using two D24s and the Serial
Point function. The master D24 records the first half of the material, and the slave D24,
which kicks in at the specified serial point, records the second half of the material.
In the following example, two D24s are used in conjunction with a digital mixing con-
sole for extended recording. The Slot Output Select function is set on the digital mixing
console so that both D24s receive the same bus signals. D24-A track outputs feed tape
returns 1–8, while those of D24-B feed tape returns 9–16.
D24-A is the wordclock and timecode master, while D24-B and the digital mixing con-
sole are wordclock and timecode slaves. Wordclock and timecode signals are transmit-
ted from D24-A to D24-B via the 15-pin sync cable.

Serial point: 00:14:30.00
A single 640 MB Overwrite-type MO disk offers 15 minutes of 8-track, 16-bit, 44.1 kHz
recording, so two D24s offer a combined 8-track recording time of 30 minutes. The
serial point time is set to zero (00:00:00.00) on D24-A, and 14 minutes, 30 seconds
(00:14:30.00) on D24-B, as shown below. The Chase function is turned on on D24-B,
which automatically chases and synchronizes to the master's timecode at the specified
serial point.
00:00:00.00
When recording or playback is started on D24-A, the D24 -B waits until the specified
serial point, at which it chases and synchronizes to D24-A's timecode and then starts
recording or playback. D24-A continues for another 30 seconds and then stops. This 30
second overlap can be used to crossfade between the slave and master D24s during play-
back.
